问题描述

我想在捕获异常后再次在try块中执行代码。

I want to execute the code in the try block again after an exception is caught. Is that possible somehow?

例如:

try
{
    //execute some code
}
catch(Exception e)
{
}

如果捕获到异常,我想再次进入try块以执行一些代码,然后再次尝试执行它。

If the exception is caught I want to go in the try block again to "execute some code" and try again to execute it.

推荐答案

将其放入循环中。

bool tryAgain = true;
while(tryAgain){
  try{
    // execute some code;
    // Maybe set tryAgain = false;
  }catch(Exception e){
    // Or maybe set tryAgain = false; here, depending upon the exception, or saved details from within the try.
  }
}

请小心避免无限循环。

更好的方法可能是将某些代码放入其自己的方法中,然后您可以根据需要在try和catch中同时调用该方法。

A better approach may be to put your "some code" within its own method, then you could call the method from both within the try and the catch as appropriate.
